Use your creativity here. Some obvious examples would be to include poetry examples, say, for Vita Sackville West. There may be You Tube performances of her poetry. Same for T.S. Eilot. You could link to the poetry examples on my blog or on sites of your choice.
Dolly mentioned the Virginia Woolf walk to visit her many houses. That is a natural. One could move jump from one to the next. The placemarks could feature pictures from the Google community, Panoramio's, or yours.
There could be references on placemarks to the film about Virginia Woolf ("The Hours"), or about Sylvia Plath ("Sylvia"). It's probably you could find some heavy Keynesian referenences, perhaps in Google Books.
If there is a composer in the Bloomsbury group, you could link that person to a performance of his or her music as I've done with the Tallis piece and (the demolished) Nonsuch Palace.
Again, feel free to use music along with your own narration. Assume limited bandwidth, so hold back a bit on what you could do. Probably two minutes is more realistic than 5 minutes as an upper limit. Go to it!
